<h2><a id="Overview">Overview</a></h2>
<p>
ZPar is a statistical natural language parser,
which performs syntactic analysis tasks including
word segmentation,
part-of-speech tagging and parsing.
ZPar supports multiple languages and multiple grammar formalisms.
ZPar has been most heavily developed for Chinese (on the Penn Chinese Treebank
and Peking University Multiview Treebank)
and English (on the Penn Treebank),
while it provides generic support for other languages and treebanks.
A Romanian model has been trained for ZPar 0.2, for example.
ZPar currently supports context free grammars (CFG),
dependency grammars and combinatory categorial grammars (CCG).

<h2><a id="System-Requirements">System Requirements</a></h2>
<p>
The ZPar software requires the following basic system configuration
</p>

<ul>
<li>
Windows, Linux or Mac
</li>
<li>
GCC (for Linux and Mac) or MinGW (for Windows)
</li>
<li>
256MB of RAM minimum (or larger depending on the modules used)
</li>
<li>
At least 500MB of hard disk space (or larger depending on the modules used)
</li>
</ul>

<h2><a id="Download-and-Installation">Download and Installation</a></h2>
<p>
Binaries and sourrces of the latest release can be downloaded from
<a href="http://sourceforge.net/projects/zpar/">sourceforge</a>.
ZPar provides functionalities for different languages and treebanks, such as
<code>zpar</code>,
<code>zpar.en</code>,
<code>zpar.zh</code>, and
<code>zpar.mvt</code>
for generic language,
English Penn Treebank,
Chinese Penn Treebank,
and Chinese multiview treebank,
respectively.
Source codes and binaries are provided for Windows, Linux and Mac.
Standalone sub-modules can be built for individual tasks,
such as
<code>segmentor</code>,
<code>postagger</code>,
<code>conparser</code>, and
<code>depparser</code>
for word segmentation,
POS-tagging,
phrase-structure parsing,
and dependency parsing.
</p>

<h2><a id="qs">Quick Start</a></h2>
<p>
ZPar can be used off the shelf by referring to the
<a href="doc/qs.html">quick start</a>;
Sub-modules such as
the word segmentor, POS-tagger and parsers
can also be used by following the detailed instructions for
the compilation, training, and usage of individual modules.
